Experiments in Kista Science Tower

This weekend, I am performing evacuation experiments together with colleagues from Lund university, Briab – Brand & Riskingenjörerna AB and DeBrand Sverige AB. The experiments are carried out in Kista Science Tower, a 32-storey skyscraper in Stockholm, within a research project on the topic of ascending stair evacuation.

During the experiments, which are performed both individually and in group, measurements are done on both physical and physiological parameters (as you can see in the above pictures), among other things including walking speeds, behaviour, respiratory frequency, oxygen consumption, heart rate and muscle activity during the evacuation. By combining all of these sources of information, the project strives to increase the understanding of ascending stair evacuation, especially in longer stairwells.

Earlier this year, a similar experiment was performed at Ideon Gateway in Lund, and later this year, in the end of October, a third experiment will be performed in one of Swedens longest escalators, namely the one in Västra Skogens underground station in Stockholm. By introducing experiments in an escalator, as a complement to traditional stairwells, the project can also deliver conclusions on potential differences between these two types of stairs.

More information about the project can be found here. In addition, Johan Norén (Briab) and Mattias Delin (DeBrand) will present the findings of a literature review on the topic of ascending stair evacuation at the PED’14 conference in October this year. Finally, a big thank you is directed to the funders of the project; Brandforsk (The Swedish Fire Research Board) and Trafikverket (The Swedish Transport Administration) for making the project happen.
